Scientists uncovered a key genetic pathway in the origin of feathers, but they found that evolution is stubborn in turning back the clock. When you purchase through links on our site, we may earn an ...

Alteration of the expression of the co-called 'Sonic Hedgehog' gene can transform feet scale and wing feathers. While a transient over-expression of the gene can permanently turn feet scales into ...

In a new study, researchers inhibited a gene during embryonic development to make chicken feathers more primitive, like the kind of simple tube-shaped proto-feathers that likely first emerged in the ...
